According to a press release launched by the World Meteorological Organization (WMO), 2020 is among the three warmest years ever recorded on Earth. In December, the international organisation had declared 2011-2020 as the warmest ever decade, with the warming development observed with every passing decade since the Nineteen Eighties.
Last 12 months, the common international temperature recorded was 14.9 levels Celsius, which was 1.2 levels Celsius above the pre-industrial degree (1850-1900). The warmest ever years recorded are 2016, 2019 and 2020, the WMO said.
In India, too, 2020 remained the eighth warmest 12 months recorded since 1901, when the India Meteorological Department (IMD) had began sustaining temperature data. The annual imply land floor air temperature over India final 12 months was 0.29 diploma Celsius.
This is a novel growth, meteorologists mentioned, as the 12 months reported the prevalence of the La Nina climate sample. This is an oceanic phenomenon when cooler than regular sea floor temperatures are recorded alongside the central and equatorial areas of the Pacific Ocean, which in flip impacts international common temperatures. The present cycle of La Nina is predicted to proceed until mid-2021.
“The exceptional heat of 2020 is despite a La Nina event, which is a temporary cooling effect,” mentioned Professor Petteri Taalas, secretary-general at the WMO.
According to the Paris Climate Agreement, international common temperatures should be managed properly under two levels Celsius of the pre-industrial period. However, with the rising proof, the newest incidence being in 2020, the activity earlier than all the international locations stays an exceptionally humongous one. The presence of heat-trapping greenhouse gases in the ambiance is one in every of the main causes for international warming.
According to the WMO’s Global Annual to Decadal Climate Update, there’s a one-in-five probability that by 2024, this temperature will exceed 1.5 levels Celsius.
